Frequently Asked Questions
Everything you need to know about limited company accounting.
You may need to file a Self Assessment Tax Return if you are self-employed, a sole trader, a landlord with rental income, or have untaxed income from savings, investments, or dividends. Additionally, if you earn over £100,000 or need to pay the High Income Child Benefit Charge, you must file. Our accountants can help you determine your obligations.
Our service includes HMRC agent registration, preparation and filing of your SA100 return, calculation of your tax liability, and identification of allowable expenses and reliefs. We also provide year-round support and proactive tax planning advice. We handle everything digitally, ensuring a smooth and accurate submission.
The SA100 process involves gathering your income and expense details, completing the form, and submitting it to HMRC. We guide you through each step, ensuring all figures are correct and all reliefs are claimed. Once we submit, HMRC calculates your final tax bill, and we help you understand any payments due.
You'll need to provide documents such as P60s, P45s, payslips, bank statements, records of any self-employment income and expenses, rental income statements, dividend vouchers, and details of any taxable benefits. Our checklist ensures you have everything ready for a hassle-free filing.
HMRC agent registration allows us to act on your behalf with HMRC. We complete a 64-8 form or do it online, and HMRC links your UTR to our account. This enables us to correspond with HMRC, submit your return, and manage your tax affairs directly.
If you miss the deadline, you'll face an automatic late-filing penalty, with further penalties if it remains outstanding. We proactively monitor deadlines and ensure your return is submitted well in advance, so you never have to worry about late penalties.
We offer a transparent fixed fee for our Self Assessment Tax Return service, with no hidden costs. The fee varies based on the complexity of your return, but we always provide a clear quote before you commit. This ensures you know exactly what to expect, with no surprises.
